Travelling in a Plane Sound.

Hi everyone this is what my Tinnitus sounds like most of the time, yet sometimes it sounds like hearing Motor Racing,there is no whistling or whooshing and can only hear it when everything is quiet and its constant.
I suppose I am lucky at the moment as I know it could be a lot worse I am just hoping and praying it does not get louder I have had it for about 18 months or so.
Dont know if it would be worth going to a specialist to see if they can help although my Doc doesent think so.
